turbo fins damaged

The question is why were they damaged? Without answering that question nobody can help you. Was it due to:

- Thrust washer damage, whole turbo replacement is required
- Overspeeding the turbo, turbo should be rebuilt/replaced
- Foreign objects entering the turbo, it's possible to just replace the wheel

It's also something that a home mechanic shouldn't do because the turbo needs to be balanced.

 

Ok, how did a plastic bag get sucked into the turbo.. Just curious.
And if the story involves beer this might be kinda funny

 

Wheel cannot be replaced separately. You install a new/reman turbo.

 

Last time I checked they still sold turbo parts individually if that's the way you want them.

To the op, a reputable shop should be able to swap in a new wheel for you depending on the turbo, there may be such a case as you need to buy the chra but you will be able to keep your housings.
